Often the whites of my eyes get a yellow tinge to them, i know this is a problem of the liver, and alcohol obviously affects it but it also happens if i havent been drinking. if i go for blood tests will it help find out why this is happening?

See 2 docs: Although jaundice (yellow eyes from liver disease) may be a factor, sunlight exposure and dry eyes can cause actinic degeneration of the sclera (white part of the eye). This leaves a yellowing called pinguecula. As to jaundice, if liver disease is present, the yellowing can occur without recent (or any) drinking, such as in hepatitis. You should be evaluated by both an internist and an eye doc.
